"Good" cholesterol

j. high-density lipoprotein

Relaxation phase of a heartbeat

b. diastole

Originate in the ventricle and cause contraction ahead of the next anticipated beat

aorta (FIB)

Blood leaving the heart flows through the great arteries into the smaller one called ___________.These become smaller and smaller until they become a capillary. Here, oxygen and nutrients enter the cell and ______ is taken away. (FIB)
